turbulators without storage

Stack temp is in the OK range. Your not letting the fire go out in the Tarm are you ? Once you fire up the Tarm and it heats the whole system the Tarm should start cycling keeping things hot. This is the state you are looking for and will keep it this way until the weather warms. You should be adding wood to the Tarm every 6 to 8 hours.
Is it possible you have a flow check valve in the circulator on the oil boiler that is causing a problem ?
Are you plumbed with 1.25" pipe ? When Tarm is running how do the pipes feel when the water starts to flow ?

I'm no expert but I'd say yes go for it. With them in I've experienced 200 degree F stack temps, so for sure the btu's are going into the tubes. Before when I first fired my Tarm solo plus 40 several years back they were left out and I had stack temps as high as 500 degrees at my stack temp probe. With clean tubes some say your stack temps will go as low as 100 degrees. sweetheat

I guess there are 2 parts to this.
Can you use turbulators without storage, and, why my oil boiler is not heating up. I don't believe they are necessarily related.
What I was thinking is, existing stack temps aren't hurting anything. They're not excessively high. So why not get the OB heating up and the system running correctly, then start tweaking it ?
If you want to drop your stack temps you can restrict primary air, but, you want to do this with a properly functioning and clean boiler. This is the same with the Termovar. My experience is that is another fine tune adjustment.
Speaking of the Tremovar. Is the Tremovar installed correctly and with the internal element facing the right direction ?

i believe the red arrow should point back to the boiler. sweetheat

I'm not 100% sure, but I think in my Solo 30 manual it stated that they do not suggest using turbulators without storage. Without storage I think it would cause the boiler to idle more, but I'm sure it depends on the situation and system setup.

dougcarlo, based on what you describe, I would not recommend turbulators for you. Four to six hundred degree stack temps are not excessive and turbulators will reduce stack temps one hundred to two hundred degrees. A little below four hundred is OK, but sustained temps below 300 and I would expect you to see significant condensation problems in your flue. With peak temps of five hundred, I am afraid that you would be seeing too low temps too frequently if you put in turbulators. Twitch is right, we do not recommend turbulators in the Solo Plus unless you are using storage - certainly if you have very high stack temps and really good draft they could work fine, but as a general rule not advised. I also would not recommend turbulators in any case if you have marginal draft.

Sounds like you boiler is producing plenty of heat (based on stack temps) so not sure why it is taking so long for your oil boiler to heat up. Are you sure that the Solo Plus is set up to heat the oil boiler? No real reason to do that unless you have a tankless coil in the oil boiler.....Is the house getting heat? If so, it could be that hot water is just short-circuiting/flowing straight through the oil boiler and going straight out to the zones without heating the oil boiler itself?

Have you tried to pipe an automatic air vent directly on top of the boiler in place of the manual vent?
That's of course if you have that tapping.

Replace the coin vent with an auto vent.
